To the calculation of the parameters of the led installation to provide the spectral composition of optical radiation during irradiation of plants

The growth and development of plants depends on the photochemical processes occurring in their cells, which is impossible without the influence of the energy of optical radiation. The use of LED sources in plants for irradiating plants, in comparison with gas-discharge lamps, has a number of advantages. When irradiating plants, it should be taken into account that different types and varieties of plants at different stages of their development require different quality parameters of photosynthetically active radiation, and the radiation spectrum is perceived by the pigment complex of the plant. The parameters of the spectrum of such radiation affect the biochemical reactions, physiological processes occurring in the plant, as well as the development of the plant as a whole. A design of an installation for irradiating plants using LEDs is proposed, as well as a method for calculating the spectral composition of radiation. The results of numerical simulation to determine the optimal quantitative composition of emitting LEDs, taking into account the height of the suspension of the irradiation installation, are presented. According to the results of calculations, the quantitative composition of LEDs is recommended for a given value of the minimum irradiance.
